AB  - Low temperature stress is one of the most important factors limiting plant growth and geographical distribution.
In order to adapt to low temperature, plants have evolved strategies to acquire cold tolerance, known as, cold
acclimation. Current molecular and genomic studies have reported that annual herbaceous and perennial woody
plants share similar cold acclimation mechanisms. However, woody perennials also require extra resilience to survive cold winters. Thus, trees have acquired complex dynamic processes to control the development of dormancy
and cold resistance, ensuring successful tolerance during the coldest winter season. In this review, we systemically
described how woody plants perceive and transduce cold stress signals through a series of physiological changes
such as calcium signaling, membrane lipid, and antioxidant changes altering downstream gene expression and
epigenetic modification, ultimately bud dormancy. We extended the discussion and reviewed the processes endogenous phytohormones play in regulating the cold stress. We believe that this review will aid in the comprehension of underlying mechanisms in plant acclimation to cold stress.
